Recall your d = rt, distance = rate * time.
now, let's say she lives "d" miles away, and so if Billy goes say at "r" mph fast to her house, he gets there in 1hr.
now, if he goes 20 mph slower, namely " r - 20 " mph, he gets there in 2 hours, same "d" miles.
So your total is 5, 3+2=5, so divide 80 by 5 and get 16. then multiply 16 by 3 to get 48 and 16 by 2 to get 32. your ratio is 48:32
The total value is:
5. 5 x 10 ^5 * 23 x 10^3 =
= $126.5 * 10^8 =
= $1.265 x 10^10
Answer: B )
Answer:
Yes
Step-by-step explanation:
Each side length of Figure A is 3 times the length of the corresponding length in Figure B, so the scale factor is 3
